What should be done for severe dermal exposure to pesticides?

In the case of severe dermal exposure to pesticides, the priority is to thoroughly decontaminate the affected area and seek appropriate medical attention. Each of the actions listed in the choices plays a role in addressing severe exposure.

Washing the affected area with soap and water is essential, as it helps to remove the pesticide from the skin and reduce further absorption. It is crucial to ensure this is done as soon as possible after exposure to mitigate potential health effects.

Seeking medical help immediately is also a critical step. Severe exposure can result in significant health risks, including systemic toxicity, and professional medical evaluation is necessary to assess and manage any potential harm.

While applying heat and ice alternately might be suggested in some contexts for managing symptoms or reactions, it is not standard practice for treating pesticide exposure and may not be safe or effective in all situations. That said, the best course of action combines immediate decontamination efforts with prompt medical evaluation, which corresponds to the understanding that multiple steps are essential in addressing severe dermal exposure effectively.

Thus, considering all actions, the approach of washing with soap and water and seeking medical help is the appropriate response to ensure that the individual receives the best possible care and reduces the risk of serious health implications.
